Question
**Probability Distribution for x** Below is a table representing a probability distribution for the discrete random variable \( x \). The table shows the possible values of \( x \) along with their corresponding probabilities \( P(x) \). | \( x \) | \( P(x) \) | |-------|--------| | 0 | 0.164 | | 1 | 0.436 | | 2 | 0.248 | | 3 | 0.124 | | 4 | 0.021 | | 5 | 0.007 | **Explanation:** - The sum of all probabilities \( P(x) \) should equal 1, as it represents a complete distribution. - Each value of \( x \) is associated with a probability \( P(x) \), indicating the likelihood of \( x \) occurring. Users can explore this table to understand the likelihood of different outcomes for the random variable \( x \). **Additional Options:** - **Print**: To print this table for reference. - **Done**: To close or finalize the interaction.

### Understanding Probability in Sleepwalking Cases The following exercise focuses on calculating the probabilities related to sleepwalking occurrences among a group of adults. A table (not shown here) provides data on the random variable \( x \), which represents the number of adults, out of a group of five, who have reported incidents of sleepwalking. Your task is to complete parts (a) through (d) with regard to this data. --- #### Exercise **a. Determine the Probability of Exactly Four Sleepwalkers** Calculate the probability that exactly four out of five adults in the group are sleepwalkers. **Instructions:** - Enter your answer as a precise integer or a decimal. - Do not round your answer. --- This exercise will aid in understanding how to apply probability calculations to real-world scenarios, such as determining the likelihood of specific outcomes among groups with known behavior patterns.
